I have been having this issue with Opera Developer where it will crash continuously at random times. I am definitely not running out of memory, and my system is very capable of running Opera. I'm running Opera Developer 44.0.2475.0. I am running Windows 10 build 15007. This issue has been happening since at least the Anniversary Update of Windows 10, when I switched to Opera. This issue does not happen to any of my other machines that run Opera Developer. Opera Developer will crash and reopen almost instantly. This happens very often. Normally, when this happens, I have a YouTube video playing in another window with a couple other tabs. For example, the last crash I had, I had one YouTube tab open with a video playing and 9 other tabs open. Thanks for your help!
